ABSTRACT:
A Schmitt trigger circuit produces synchronizing signals during and of a pulse width equal to the positive half cycles of an alternating current input signal. A monostable multivibrator circuit is triggered to the alternate state by the leading edge of each synchronizing signal and the resulting series of alternate state output signals charges a capacitor to a direct current potential level range signal directly proportional to the frequency of the input signal. A direct current potential ramp timing signal generating circuit, which is reset and disenabled by the leading edge and enabled by the trailing edge of the synchronizing signals, generates a timing signal which increases linearly in potential level at a rate determined by the range signal. A potential level detector circuit responsive to the timing signal and a delay signal of a selectable direct current potential level produces an output signal when the potential level of the timing signal increases to that of the delay signal.
